摘要：
The invention relates to an oral care device for teeth whitening or other purpose. The device is designed to provide a uniform light intensity distribution at the teeth by use of a light mixing chamber of a mouthpiece comprised by the oral care device. The mouthpiece comprises a sealing structure with rims designed to connect to the gums of a user. At least apart of the rim and a closure of the mouthpiece surrounded by the rim are reflective. When light is emitted into the mouthpiece, the light will be reflected by the reflective rim, the reflective closure and the buccal side of the teeth. Accordingly, the light will be reflected multiple times, which makes the intensity distribution more uniform. Additionally, the mouthpiece may comprise light redirection structures arranged to redirect light rays from light injected into the mouthpiece.
